To all 'zirhom- K. may concern Be ll known that I, THOMAS J. CLARK, :1 ClilZ'dXl of the United States, and a resident of lvlilwnnhce, C lachanins oouniy, State of fliw an gnome mAICLb 0/1 ul lllcO n'eveniing such slipof my invention is to which Will not injure the Way when the latter are rollin-q; on a hard surface.

Tillie pl'lllClplll features of my device coin-. prise hinged lip adapted to swing outivni-dlj. from the vehicle wheel; a cleniping are; emenl by which my de ice may he i no-.. and securcl} attached to a ehicle wheel; and .dguiuhle means by which any.

device may be adapted for use on Wheels of different sizes. Tnese and other incidental features are full illustinted in ihe accompanying ihmvings i'oi'ining 2i pir'l of this specnicanon.

In the drawings: Figure 1 is a fragmeni side elevation of on automobile Wheel, lowing my device attached to the some; in iis view it is to be assumed that the Wheel. is slippin ire-innfei'eniinlly in the direction indicnted b, the arrow A and the hinged lip havin wung outwardly from the wheel is so 90s ioned as lo dig into the road-bed;

Fig. 2 is a radial sccl ion taken HPPLIJXlnnitely on the line 13- 2 of Fig. 1, looking in i'he dii'cc'tiol'i pointed the ill'lOW B and drawn to a larger scale the purpose of clcai'ness; the full lines oi this figure show my device in its position on lhe illC, but not fastened thereto, While the broken lines of such figure show the device firmly clamped in position; Fig. 3 is a larger-size detail of certain parts of my device as shown in Fig. 1.; the full lines of this view show the posit-ion assumed by said parts when the Wheel is revolved to drive the vehicle for-- ward, and the dotted lines showing the position assumed by the lip,-whcn said Wheel rolls in the opposite direction. Fig. ei is a perspective view of that portion of my device which bears on the eXiellOl of the wheel, that is, the saddle and the hinged lip; Fig. 5 is a plan view of the clamping device illustrated in Fig. 2, showing the same in a ulosed'or locked position; and Fig. 6 is a fragmentary radial section of an automobile Wheel showing how the details of my clampingg, device may be arranged to fit dififerent forms of fellies.

The pneumatic the, a, is mounted on a vehicle Wheel 8, the felly of said vvhccl being indicated by b, the clencher rini by p, and the spokes by d. A saddle, e, is adapted so he snugly over the tire a when the latter inflated. Attached he the sides of said saddle are the chains f, g, and on the exteiior face oi this saddle is a lug h. A movable lip, i, is hinged to the saddle, e, by the knuckles 'y'. On the lower surface of said lip is a lug or stop Zr, arranged so that when the lip moves in a clockwise di 7 i'eetion the lug 7c will, Contact with the lug h, and prevent a. i ether movement in that direction. See Fig. 3.

A strap, Z, adapted to fit over the felly, has an inner lining of soft material, m, such as felt, so that said folly will not be scratched or injured in any Way by the attachment of my device. The strap, Z, is provided with two longitudinally extending shouldeied portions, n, 0, s0 arranged that they will hear on the clencher rim, 29,.tl1ercby peevcntiiig the entire strain from falling on tile telly. Said shoulders also provide convenient means for fastening the connections \vhich exiend between the strap, Z, and the saddle c. Anndjustnble bolt, held in place-B31 21 nut 9*, beers in the shoulder 0 and has fastened to its lower end the chain The working end of the bolt, 9, may be lengthened o1 shortened, thereby adjusting the tension in the chains, f, g, i1s desired.

The shoulder, n, has on its outer extremity an e211 8 supporting :1 pin a: on Whichds pivotally mounted, a lever Z; This leveris oi such a form that when in the act of clamping my device in place the lever is rotated counter-clockwise to the position shown-in the broken lines of Fig. 2, it will rest on the strapZ. The lever t 18 provided with a slot at, in which bears a hook v, adapted to be connected with the end link of the chain 9. When said chain and hook are connected the lever is rotated on its fulcrum pin, :8, until it is positioned as shown in the dotted lines of Fig. 2. This movement of the hook, 4:, causes a consequent tightening of the chain 9', thereby clamping the saddle e firmly on the tire. By reason of the resultant downward. pull being applied to the lever inside the fulcrum of the latter, the tension in the chain 9 serves to hold said lever firmly in its clamped position.

A ring, w, fastened to the end of the lever;

is to be removed from the vehicle Wheel. 1

In Fig. 6 the parts shown act functionally difference bein only in the construction of saidparts whic i are adapted to be used with -wheels having fellies of different styles than that shown in Fig. 2.

I claim:

1. A non-slip attachment 'for vehicle wheels comprising a saddle adapted to fit over the vehicle tire, an inflexible lip hinged to the saddle, the lip arranged to swing outwardly from the tire, and means for clamping said device on a vehicle tire.

2 A non-slip attachment for vehicle wheels comprising a saddle adapted to lit over the vehicle tire, an inflexible lip hinged to the saddle, the lip arranged to swing outwardly from the tire, means which limit the swinging movement of said lip, and means for clamping said device on a vehicle tire.
